Definition of validation
Three commonly used definition of validation process:
[1]
Validation is defined as a process for assessing simulation modeling
unertainty by using benchmark experimental data and, when conditions
permit, estimating the sign and magnitude of the modling error itself
[2]
Validation ~ solving the right equtions
[3]
Validation: the process of determining the degree to which a model is
an accurate representation of the real world from the perspective
of the intended uses of the model
